Preparation and properties of ethylene-acrylate salt ionomer/polypropylene antistatic alloy

Ethylene-acrylate salt ionomer antistatic agent was prepared with ethylene-ethyl acrylate copolymer and potassium hydroxide as the primary raw materials and blended with polypropylene (PP) to make self-made ionomer/PP antistatic alloy. Commercial Entira and PP were blended in the same way to prepare Entira/PP antistatic alloy. Then, the morphological and physical properties of the self-made ionomer/PP and Entira/PP were studied using differential scanning calorimetry, thermo-gravimetric analysis, rotary rheometer, and scanning electron microscope. The experimental results showed the development of a self-made ionomer in a torque rheometer successfully, and its performance in all aspects was similar to the commercial Entira. Material test results have shown that the physical properties such as surface and volume resistivity, antistatic durability, thermal weight loss, crystallization properties, and rheological properties of PP modified by self-made ionomer are very similar to those modified by Entira. And due to the selection of raw materials, this self-made ionic antistatic agent is cheaper than commercial Entira and has good research value.

Automated summary

A self-made ionomer antistatic agent was successfully developed for the preparation of ionomer/PP antistatic alloy, showing similar performance to the commercial product Entira. Material test results revealed that PP modified by the self-made ionomer exhibited physical properties very similar to those modified by Entira, indicating potential for research and application.
